If the corrosion rate of the coupon is greater than 0.25mm/a, it is considered severe corrosion. Which one is this?* * Standard definition? Thanks!
The definition of coupon corrosion rate is stipulated by the standards established by the International Organization for Standardization (ISO). As for the definition of severe corrosion with a coupon corrosion rate greater than 0.25mm/a, it is currently impossible to determine which one it is. * * defined by the standard. because different * * Different regions and regions may use different criteria to define severe corrosion. .
C5 environmental corrosion is 80-200μm per year. Refer to C5, this corrosion is higher than c5. It should not be a problem if it is defined as severe corrosion. Severe corrosion is a sensory concept and cannot be quantified. For reference only
